More Information

A hyperlink may not go to a Microsoft Word document or a Microsoft Excel worksheet after you use this workaround.

Office uses the Urlmon.dll file to handle all Internet transitions.

In this case, the Urlmon.dll file sends a request to get a file via http:// through the proxy server. The proxy server sees that the request came from Internet Explorer, based upon the HTTP User Agent field of the http://request. It then gives an error 403, basically saying 'Access Denied.'

The Urlmon.dll file gets this and simply returns the error message mentioned earlier. The error means that the request failed, but it never states why it failed.

The workaround is to simply use a ShellExecute() on the URL. This allows the operating system to start the URL on the default browser. If the default browser is not restricted by the proxy server, the proper page is displayed.
